Factual and proportionate objections to the person are legitimate here – but insults, unsubstantiated allegations, and irrelevant personal details remain fallacious even in this context. - A speaker feels personally offended by a *factual* contradiction of their views (especially on religious, political, or ideological topics) and labels it "ad hominem." Factual disagreement with a position is not an attack on the person holding it. ## Commonly confused with - **[Appeal to Authority](relevance/authority/index)** ([MD](relevance/authority/index.md)) – invokes someone's status or credentials as *positive* evidence for a claim. Ask: is the person's authority being used to *support* a claim (→ appeal to authority), or is their person being attacked to *dismiss* a claim they made (→ ad hominem)? - **Red Herring / Distraction** – introduces an irrelevant topic to divert attention from the actual argument. Ad hominem is a specific subtype of red herring that targets the *person*. Ask: does the diversion specifically target the identity, character, or associations of the arguer (→ ad hominem), or is it about an unrelated subject matter entirely? ## Examples > **Input:** "Why should we listen to her climate policy proposal? She's a career politician who only cares about getting re-elected." > **Output:** The speaker's political motivations do not determine whether the policy proposal is sound. Evaluate the proposal on its merits; if there are factual errors or logical gaps in it, point those out specifically rather than dismissing the whole thing based on who proposed it. > **Input:** "You're just saying that because you work for a tech company – of course you'd argue that AI regulation is 'too strict'." > **Output:** Alleging a potential conflict of interest (ad circumstantiam) may be worth noting as context, but it does not automatically invalidate every claim the person makes. Address whether the specific argument is correct on its own terms; flag the bias separately if relevant to how their evidence was gathered.
